1 VDDR PWR
3.3V power for differential input clock (receiver). This VDD should be treated as an
analog power rail and filtered appropriately.
2 SRC_IN IN 0.7 V Differential SRC TRUE input
3 SRC_IN# IN 0.7 V Differential SRC COMPLEMENTARY input
4 GND PWR Ground pin.
5 VDD PWR Power supply, nominal 3.3V
6 DIF_1 OUT 0.7V differential true clock output
7 DIF_1# OUT 0.7V differential Complementary clock output
8OE1# IN
Active low input for enabling DIF pair 1.
1 =disable outputs, 0 = enable outputs
9 DIF_2 OUT 0.7V differential true clock output
10 DIF_2# OUT 0.7V differential Complementary clock output
11 VDD PWR Power supply, nominal 3.3V
12 BYP#_HIBW_LOBW IN Tri-level input to select bypass mode, Hi BW PLL, or Lo BW PLL mode
13 SMBCLK IN Clock pin of SMBUS circuitry, 5V tolerant
14 SMBDAT I/O Data pin of SMBUS circuitry, 5V tolerant
15 GND PWR Ground pin.
16 VDD PWR Power supply, nominal 3.3V
17 SMB_ADR_tri IN
SMBus address select bit. This is a tri-level input that decodes 1 of 3 SMBus
Addresses.
18 VDD PWR Power supply, nominal 3.3V
19 DIF_5# OUT 0.7V differential Complementary clock output
20 DIF_5 OUT 0.7V differential true clock output
21 OE6# IN
Active low input for enabling DIF pair 6.
1 =disable outputs, 0 = enable outputs
22 DIF_6# OUT 0.7V differential Complementary clock output
23 DIF_6 OUT 0.7V differential true clock output
24 VDD PWR Power supply, nominal 3.3V
25 PD# IN
Asynchronous active low input pin used to power down the device. The internal
clocks are disabled and the VCO and the crystal osc. (if any) are stopped.
26 IREF OUT
This pin establishes the reference for the differential current-mode output pairs. It
requires a fixed precision resistor to ground. 475ohm is the standard value for
